CURTAIN-POLE.

Specication of Letters '.E'atent. Patented Sept. 10, 1912, Applicationfiled August 25, 1911. Serial No. 646,03.

To all whom it may concern:

Be it known that LQHENRY A. ANDERSON, a citizen of the United States,residing at Missoula, county of Missoula, and State of| Montana, haveinvented certain new and useful Improvements in Curtain-Poles, of whichthe following isa specification.

, My invention relates to curtain .poles and particularly to poles forcurtains and portires 4'which may be adjusted in length-tol suit thewidth of the Window or door where .they are -to be used.

The object of my invention is to provide a pole of the class mentioned.which may be readily adjusted in length and which, when adjusted, willhold the brackets or support in position' on the lwindow or door frame.

A further object of my invention is to provide an adjustable pole of theclass under consideration equipped with means whereby it may be adaptedfor use lwith `consists 'generally in a curtain pole com prismg acentral tubular portion, a pa1r of'end portions telescoping thereiuto,means for locking said portions against relative movement and meansthreaded Kupon Athe outer ends of the last said portions for engagingthe supports and clamping the same against the window or door frames.

My inventionl further consistsin various.,

details of construction and arrangements of ,parts all as will be fullydescribed hereinafter and particularlypointed out in the claims.

My invention will bey more readily understood byreference to theaccompanying drawings forming a part of this specication and lin Which-Figure 1 is a plan view,"partially in section, of a curtain poleembodying my invention, and illustrating the same in conjunction with abracket such as is used for supporting the pole upon a window frame.Fig. 2 is a similar view 'illustrating the pole in `conjunction withsocket supports, and "I equipped with means for engaging 'the sockets,Fig. 3 is a detail sectional View illustrating the locking means, Fig. 4is a section on the line -m of Fig. 3, and F ig.` 5 is a perspectiveview of one ofthev brackets.

Referring now tothe drawings 1 indi- I cates the central portion of thepole and 2 indicates the end portions. rlhe portions 1 and 2 are tubularand the latter telescope within the former `by which construction thelength of the pole may be adjusted. The outer ends of the portions 2lareclosed by means of caps 3. The inner end of each of the portions 2 issplit, asindicated at 4,

and arranged within each of the split ends `1s a frusto-conleal member5, the larger end ofewhlch 1s of greater dlameter than` the yinternaldiameter of thetubular por@ tion 2.. `It is obvious that by drawing themember 5`within the split endof the member 2, said end will be expandedand bind .tightly within the member 1, thereby lock- -mg the members 1and 2 against relative The'member 5 1sy longitudinal movement. securedto the end of arod Gwhich extends through the respective member 2 andprojects beyond the end thereof, the proj ectingend being threaded asindicated at 7.

When the device is used with a bracket the end-7 is projected through anaperture in the arm of the bracket and a ball end 8 is threaded thereon.The poleis adjusted in leugthto fit between the arms of the brackets, asshown in Fig. 1, and as'the balls are screwed upon ,the ends of the rodsf G they will engage the outer .facesof the bracket arms and draw therod forcing the member 5 within the' split end' of the mein-Y ber 2.

. The bracket which is preferably used with' the pole comprises a plate-9 adapted to rest against the outer fece of a window casing A, a tongueextending outwardly at right angles to the plate 9 and bent back uponitself forming parallel portions 10 and 11 constituting the arm of thebracket, and ears 12 extehding in the opposite Adirection from the armand provided with prongs 13 which engage into the edges of the windoweasing The portions 1 0 and 1l are provided `witli perforations 14 torece1ve the end of the rod 6. When the halls 8 are threaded upon therods they will engage theouter portion 10 of the bracket arms and clampthe brackets securely upon the Window casing.

In F ig. 2 I have illustrated the device as used in conjunction withsockets -,upon the inner faces of door jambs B. When used in this mannerthe pole is equipped 'with a sleeve 16 threaded upon the end of the rod6 and bearing against the cap 3, by

means of which the member 5 may be operated. The sleeve 16 is providedWith a peripheral flange 17 to facilitate turning the same and alsoserving to ornament the device. The outer end of the sleeve 16 isthreaded as at 1S and threaded thereon is a member 19 having a lug 2O toengage an aperture 21 in the socket member 15. n using the. device themember 19 is retracted upon the sleeve 16 and the pole adjusted to theproper length. The sleeve 16 is then turnet. to lock the portions l and2 and ,the members 19 turned upon the sleeve to l engage the socketmembers., and force the of each of the end sections for locking saidstantially as described.

2. In a curtain pole, a central tubular section, a pair of end sectionstelescopng thereinto, the Y inner ends of said end sections beinglongitudinally split, rusto-conical members projecting into said splitends, a rod'ixed to each of said members'and extending through therespective end sections, saidrods projecting beyond the ends of thesections and threaded, members threaded upon the projecting ends of saidrods, the outer ends of the last said members being exteriorly threadedand support engaging members threaded upon said ends, substantially asdescribed.

ln testimony whereof I have signed my name tov this specification in thepresence of two subscribing witnesses.

HENRY A. ANDERSON.
